And welcome to part five of our artificial intelligences in Starcraft two with python tutorial.

Hopefully we can secure our very first victory.

And, um, the way we're gonna do it is we're already started building our army, and now all we have to do is get some logic built to attack the enemy.

Basically, um, and our hope is that the enemy will be easy enough that we can do this with pretty simple logic.

So, uh, with that, really all we need Thio ad in like we're already building our army.

So the only thing that we need to add in is away itself dot attack.

So some sort of logic that we can employ to actually attack the enemy.

So I'm gonna come down here and I'm gonna do a sink, uh, passing himself.

And what are our rules going to be four actually attacking.

So we probably like you don't want to, like, attack with every new stalker that you create.

So instead, what we're gonna do is once we have a certain number of these stalker units, we're gonna send them in to battle, so we could go with anything.

Um, I think I'll start maybe with 10 or something like that.

So if self die units stalker, um mesh, veal calves, stalker, uh, dot amount is greater than it'll be five.

So if we have more than five stalkers, what we're gonna want to do is send them into battle.

So we're gonna say four s so stalker in self dot units stalker.

And we want to do stalkers that aren't currently doing something.

So the ones that are idle, what we want them to do for s what we want them to do is await self dot Do so this is kind of like the overarching agent self dot Do and we want to make s attack.

You have to like, when you say attack, they have to choose, Like, what are we actually going to attack?

So we're just gonna attack, um, so you can do like, self dot known and in me units.

So we saw that before again, That's a method that exists inside of bought a I.

So that's like, appear, I think known enemy units.

So let's say we see an enemy unit, we know we can attack them.

So we're gonna just was gonna look for, um, for one of those, um, So if we have greater than five, let's just go ahead and attack an enemy unit.

Um, And the way the way that we're gonna do that is this is like, a list self dot known enemy units.

So we actually want to do something like a random dot choice of known enemy units.

Okay, So before I forget, let me go ahead and, uh, import random up here.

Now, that's all fine and dandy, but there might not actually be.

And I mean, like, any known, um, enemy units.

So the other thing that we could say is, um, see random choice in Well, let's go and run this, actually, and let's just, uh well, it's a real time false, and we'll just see if they'll actually go after any of the Attackers against us.

That might take way too long to get us up to 10 so we might wanna.

We probably want to change that logic slightly.

So, um, there's a few things that we probably need to consider.

Hopefully lets you Maybe we'll get away with building enough.

Uh oh, no, we only chose five, so it'll only take five.

So as soon as an enemy shows up, we should see these little guys run off and go yet.

Okay, so they're already defending us, destroying the enemy.

Durn Okay, So probably what we should do is like a So So what we should say is, um we probably need to check this.

So, like, if so, what we could say is if Len, um, self dot known underscore enemy units if that length is greater than zero, so if that's more than zero, let's go get him.

Okay, so that's a good, like defensive strategy.

But then we might want it like we might actually want to do something Maur like.

Like if we have a large enough army, we'd like to probably seek out our enemies.

So, like, if self units stalker dot amount is greater than, let's say 15.

So if we have more than 15 of these stalkers, what we're going to say is, uh, well, just copy this line here.

So for each of this idol stalkers, what we should do is find something to attack.

We're gonna have to make a new function, I think.

But what will say is, um so for each of those stalkers, what we're gonna do is we're gonna await, uh, self dot do s attack.

And then again, we need to attack something and think time or it's a self dot find target.

And then we're gonna pass self dot state.

So this will just be like the game state.

So then I'm gonna go above here and I'm gonna write this fine target function so deaf, find target.

And this is just a simple function and in this case will take an arm Sorry method, and we're gonna take in self and then the game state that we're passing in and what we're gonna look, what we're gonna do is like so first forward to say, if Len of self dot known enemy units if that's greater than zero, let's go ahead and just attack the known enemy units.

Um, so we're just gonna say return random dot choice, self dot um, known enemy units.

So if we know about some sort of enemy unit, we're gonna go for those first.

And then what we're gonna dio is, um LF, len, self dot known enemy and any structures So if we can't find any units to attack, we're gonna go for the structures themselves.

So if that's greater than zero, we're gonna return random dot choice self dot known enemy structures, and then finally, else we're gonna return self dot enemy on and me start location zero with.

So, in this case, when we have one enemy, so it's gonna be the zero with enemy.

But this is how we're gonna how we're gonna opt for, like, we just want to go on attack, right?

So once we have a large enough army, we're just gonna go after all the known enemy units um, And then we're gonna go after all the known enemy buildings.

And if we don't know about any of the enemy building so way haven't seen anything about our enemy yet, we're just gonna be like, Well, we know where the enemy started, so we know, seek them out at their start location.

And I guarantee we're gonna find something there, Right?

So So in this case, if this is the case, we go ahead and do this and then this should probably be, um l if down here.

So if we have a large enough army, we're gonna do army things.

We're gonna just seek out the enemy and destroy if we don't have an army.

But we have enough units, and I think I'll change this.

Actually, three, we have enough units to, like, somewhat defend ourselves.

Ah, well, go ahead and do that s o The next thing I want to do before we do this is we want to be ableto have enough gateway building.

So here's our offensive force buildings, and what we want to dio is we want to build, so we want to build that cybernetics core.

So if self um, let's see, pylon come on is like rewrite dysfunction.

But basically what we want to do is we're gonna build the cybernetics core if this exists.

What we should do is itself, like a way already exists.

I think what I'd like to do is maybe do because we want to grab the pylon and then we on Lee.

We really it's hard to decide if I want to build because you want to build the cybernetics core as soon as you have a gateway.

But then you also build cybernetics core, if not cybernetics core.

So maybe if a gateway exists and no, it cybernetics core, we want to go ahead and do this.

So if we have a gateway already and we don't have a cybernetics core, build the cybernetics core.
